roALLwHoM IT MAY CONCERN:

Be it known that I, ROBERT TYRRELL,,Of Summer, in the county ofLawrence, and State of I llinois, have invented a new and usefullmprovement in Tire Bending Machines and I do hereby declare thatthefollowing is a full, clear, and exactdescription thereof, which willenable others skilled in the art to make and use the same, referencebeing had to the accompanying drawings, forming partof thisspecification, in which Figure 1 is a side view of myvinvention. Figure2 is atop view of the same." 'Similar letters of reference indicate likeparts. The object of this'invention is to accomplish the bending ofwagon-tire in an easy and expeditious manner. It consists of'a revolvingdisk, operated by a lever-arm, by means of which the tire is drawnbetween the periphery of the disk and a roller-wheel, and bentaround-the diskQ I A is the disk, having the lever-arm B afli'xed acrossits top, by uprights .5 d, cast on'or aflixed to the disk,

and which are of sufiicient height to pass the lever-arm clear of thejaw D, which furnishes the upper'bearing of the shaft of theroller-wheel O. r

Clamp-plates g g are aflixed tojthe disk as shown, and provided withholes for. the reception of the.pin 10,

which'elamps the 'end of the tire to the disk, as shown at fig. 2. j

The disk is provided with two circular surfaces, e and f, suitableforthefore and bind wheels of wagons, and the'clamp-plates are provided withanother. and inner set of holes for the pin 12, when the smaller'circle,e is being used. V

The tire z' is drawn in betweeuthe disk and throller-wheel, when theformer is revolved in the manner shown at fig. 2, and one completerevolution of the disk accomplishes the formation of a wagon-tire frou;the bar. The disk is formed with a gudgeon, k,-which fits within thestep-bearing, Z, and the latter passesthrough the frame ortrestle-hbrseH H I G, and is afiixed thereto as shown. I

The bearings of theroller-wheel are in the jaw D and the'plate gt, thelatter beingi'ormed withflange-plates m, to hold it upon the beam G. I rr j The jaw D and plate at are clamped to the beam G'by means of abolt-rod, 1', having a head, k, andnut and washer, 7'. Thisbolt-rod-passes down through the slotted extension, E, of the jaw, andsimilar slotted extension of theplate n, which lies immediately beneath.

By means of these slots the roller-wheelmaybeset upto the smallercircle, e, when the latteris being used or adjusted generally to eachcircle, to accommodate any thickness of bar-iron. 1 l

The block 0, for the purpose of adjusting the height of the roller-wheelto either the larger or smaller'circle -of the disk. This block isslotted to permit the passage of the holt-rod, and when used to raisethe roller-wheel to its upper posit-ion, the block is withdrawn from itsplace, under the beam, and placed between the plate n and the beam-theprojection q fitting into a corresponding hole in the beam, and theflanges m fitting on the block as they did upon thebeam. j Thewheel isflanged, and in} connection with the flange c cf'the disk, prevents the"tire from getting 011 y from the bending-circle.

.Having thus described my invention, I. claimas n'ew,-and desire to.secure by Letters Patent- The combination of therotary disk A ,-havingthe two d'iameters, efi and prdvided with the lever 'B and clampingdevice g h, with'the horizontally and vertically-adjustable roller 0,slotted arm D E, block'sn a, headed red It, provided withthe nut j andg'udgeohih-all constructed and arranged to operate substantially asherein set forth.
